My big sister Vanessa gave me a cupcake for my birthday from my most favorite bakery. I didn't expect a gift from her at all. She also gave me a little vibrator with a remote control. I've never seen one of these before. She tells me to put in down my panties on my clit. I told her it feels funny down there. She keeps asking me questions about my sexual experience. I keep telling her that I haven't had any! I mean, I'm only turning 18 today! She can't believe I don't already play with vibrators and says that it should make me feel the way I feel when I'm making out with a guy. I told her I haven't made out with any guys. I haven't seen or touched a guy's dick. I wouldn't know what to do with it anyway. She immediately remedies this situation by bringing our step-brother in as a cock model for me. I can't believe she wants me to touch my brothers penis! So gross! I certainly don't want Mom and Dad to find out about this. We all agree this is my 18th birthday secret and none of us will tell anyone, not even our friends. My sister insists she cant send me to college without knowing what to do with a cock. I am still a little hesitant because this is kind of weird to me. I also don't want to look like an inexperienced prude to those college boys so I reluctantly grab a hold of his pole like she instructs me to. She said she was getting all kinds of dick way before she was 18 so I trust her to guide me through this embarrassing yet intriguing set up. I think she knew exactly what she was doing when she gave me my gifts today because she also included a tube of lube in my gift bag. She had me squirt some on his growing shaft and then she showed me how to move my hand up and down to get him really hard. She made it look so easy. She told me I was a good girl doing a good job. She even showed me how to play with his balls. They felt weird but I liked it. Who would have thought my first dick I touch would be my step-brother's. It looked like my brother was really into watching us jerk him off. My sister suggested we get completely naked and then told our brother to look at my virgin pussy! How embarrassing! It made me giggle though because I was being so naughty. I'm never the naughty one, my big sister Vanessa always is. I like that she was willing to teach me what to do with the first cock my hands touched. Keeping the sexual education all in the family made me feel safe. My sister laid back and let him see her pretty pink pussy so I could jerk him to cumming on my little hands. I tell him to cum really nice and big for me. It is my first time after all and I want to see what a dick does when it shoots its goo. My sister says he's a squirter. I guess she said that cause his goo almost shot up into my hair! As I am making my brother squirm by continuing to rub his super sensitive post cum shaft I thank my sister for teaching me this important rite of passage on my 18th birthday.
